Where I live there is very little badminton going on in spite of some good facilities. The problem seems to be getting youngsters to take an interest in it instead of computer games and their phones. There are very few adult players but it would be useful to generate local interest except I cannot see an incentive for them to get involved.
This problem has been around for at least 25 years.
When I was younger, my Mum would make me do Hockey at a junior club. It was ok, then a friend stopped going, then I decided I would rather spend my Sunday mornings playing video games and watching tv etc. I did like the sport, but I would get terrible shin splints from running on the pitch. I regret giving up a tiny bit, and when I tried to do it again some 20 years later... still had the shin splints issue.
I picked up badminton properly when I was about 21 and i've stuck with it. I'm not great at things like football, darts etc. But badminton is a sport I do well in and can improve.

I understand this problem. Sometimes it's down to the venues and how they are run. The local Leisure Centre where I live regularly book out the hall and give badminton players the middle finger so to say. We literally block book whole months and maybe with 2 weeks notice they will say "sorry, tough the hall isn't available that day". They also charge a ridiculous amount for a court (like £16 for an hour of play). We've complained to Badminton England and nothing came about from it.

Best way in my opinion is to get the kids playing. Have a motivational person or coach in charge of the session and make it fun. I forget the name of it, but it was something like "smash time" and it was an after school club initiative thing to get kids interested. "No strings" is good on the whole but is more aimed at Adults and the session quality varies depending on where you go.

It would be great if more adults just got playing with their children / family and got them interested in it.
